The study showed that monthly pulses of intravenous methylprednisolone (IVMP) are safe, well-tolerated, and effective in reducing seizures and improving global outcomes in children with epileptic encephalopathy (EE). Children with idiopathic EE, normal neuroimaging, myoclonic jerks, and West syndrome had the best response to the treatment.
Objectives: To study the effect of monthly pulses of intravenous methylprednisolone (IVMP) on seizure and global outcomes in children with epileptic encephalopathy (EE). Methods: This retrospective study was undertaken in a tertiary care epilepsy center in India. Consecutive patients with EE who had received IVMP as adjunctive therapy for a minimum of 3 months and had at least one pre-and post-steroid EEG each, were identified and a structured questionnaire was used to collect information including outcomes at 3 months post-steroid course completion and beyond, as available. Results: Ninety-seven patients (M:F=71:26) fulfilling the inclusion criteria with a mean age at onset of seizures being 20.52 +/- 25.69 months were included. Commonest seizure types were myoclonic (66%); Lennaux-Gastaut and West Syndromes accounted for 57 % and 24 % patients respectively. The etiology was unknown in 52 %. All children were on a combination of standard anti-seizure drugs. The duration of IVMP pulse therapy was 7.72 +/- 6.25 months. One-fourth (26 %) patients experienced minor adverse events. Greater than 50 % seizure burden reduction was seen in 66 % patients at 3 months with seizure-freedom in 25 %. A total of 45 (46 %) patients became seizure-free in the cohort eventually with continuation of steroids beyond 3 months. Children with idiopathic EEs, normal neuroimaging, myoclonic jerks, and West syndrome showed the best response. The presence of burst-suppression and generalized paroxysmal fast activity (GPFA) predicted inadequate response. Conclusions: Adjunct pulse doses of IVMP are safe, well-tolerated, and effective in reducing seizures and improving global outcomes in children with idiopathic EEs, West syndrome, normal neuroimaging, and myoclonic jerks. Seizure freedom might be delayed in a subset of these patients, hence duration of therapy beyond 3 months may be warranted.
